Analysis of Case Study
initial analysis: Most important thing to note is that the average usage for Bay Area counties are consistently lower than LA county usage. Overall California trend, LA, and Bay area all follow similar seasonal changes in usage.

Overview analysis/comments
So the first “overview” maps may be too much to put into the presentation, because the image needs to be very large to show anything useful. I definitely think the contrast is good to see, but maybe the “Previous Drought” and the “Current Drought” maps will be enough to show how much worse off we are currently. Again, I think this in conjunction with the plot that Tiff made will be good together
Comments
Well this one doesn’t necessarily need to be used since we have better maps below, but if you did want to include this I would mention how in the two previous droughts in California, no counties reached “Exceptional Drought” levels, in contrast to 2014-2016 when multiple counties are registering as having “Exceptional Drought” levels. This in conjunction with Tiffany’s plot of # of counties vs drought level would be interesting side by side, because in these maps you can see that for 2014 and 2015 there were no counties that had “NONE” or no level of drought, and in 2016 we see some counties highlighted again. So Tiffany’s plot should tell us what number of counties there are that have “NONE” while this one shows where.
